 Log Message:
 PR/32682: Hauke Fath: netbsd-3 ptyfs intermittent failure with Matlab
 
 For the benefit of linux emulation create a new minor device '2'
 which is a ptmx with linux semantics. Linux changes the permissions
 of the slave pty upon creation, not when grantpt(3) is called. The
 glibc linux grantpt(3) checks that the pty is on ptyfs, and if it is,
 it does nothing. To make use of this fix:
 
 	mknod /emul/linux/dev/ptmx c 165 2
 	chmod 666 /emul/linux/dev/ptmx
 
 This is a lot simpler than copying a bunch of code and creating a
 ptmx device just for the benefit of linux emulation.
